Bacterial magnetosomes (BMs) are commonly used as vehicles for certain enzymes, nucleic acids and antibodies, although they have never been considered drug carriers. To evaluate the clinical potential of BMs extracted from Magnetospirillum gryphiswaldense in cancer therapy, doxorubicin (DOX) was loaded onto the purified BMs at a ratio of 0.87 +/- 0.08 mg/mg(More)
Magnetotactic bacteria are difficult to grow under defined conditions in culture, which has presented a major obstacle to commercial application of magnetosomes. We studied the relationships among the cell growth, magnetosome formation, dissolved oxygen concentration (DO), and the ability to supply oxygen to the cells. Mass culture of Magnetospirillum(More)
Bacterial magnetosomes (BMs) have drawn great interest as novel magnetic targeted carriers and have been widely used as carriers for enzymes, nucleic acids and antibodies experimentally. However, BMs have rarely been employed as drug carriers in vivo mainly due to the unclear biocompatibility and pharmacokinetics of BMs. In this study, we provided a unique(More)
Hepatocellular carcinoma (HCC) is the most common form of cancer although effective therapeutic strategy especially targeted therapy is lacking. We recently employed bacterial magnetosomes (BMs) as the magnetic-targeted drug carrier and found an antitumor effect of doxorubicin (DOX)-loaded BMs (DBMs) in EMT-6 and HL60 cell lines. The aim of this study was(More)
